| Fundamentals
Focus groups serve much the same function as individual
interviews. The main difference is that, with focus
groups, the questions are asked of groups. Focus groups
have an advantage over individual interviews because
the comments of one participant can stimulate the thoughts
and ideas of another. On the other hand, some participants
might not be willing to divulge sensitive or personal
information in the presence of others.
Many of the same questions may be used for individual
interviews and for focus groups. As in individual interviews,
in focus groups the evaluator looks for insightful comments
and common threads and uses direct quotes as the evaluation
data. In focus groups, however, important themes and
common threads are sought across groups as well as individuals.
The data are not restricted to points of agreement,
but may also emphasize differences among participants.
To get the best information, it is important to conduct
more than one focus group because different combinations
of people will give different perspectives. A minimum
of three focus groups is usually recommended; the more
views expressed, the more likely you are to develop
a good understanding of the situation.
Many times it is useful to group people with a similar
relationship to the program within a group. For example,
it might be better to conduct one group with persons
who refused to participate in the program and another
group with those who completed it, than to put the two
together in one group. This allows group members to
find common ground for discussion, and go into greater
depth. Also, grouping members who view themselves as
equals allows all members of the group to express their
opinions freely.
Like individual interviews, focus groups are audio-
or videotaped, and the tapes are transcribed for analysis.
It can be useful to have more than one recording device,
in case of mechanical failure.
When each focus group is completed, the facilitators
and recorders of the group analyze the data. Data from
earlier groups can guide the way questions are asked
in later groups. When all the focus groups are completed,
facilitators and recorders complete the final analysis.
This is done by developing a summary of the combined
groups, noting group differences and suggesting hypotheses
about those differences. When the analysis is complete,
the evaluator prepares a written report for program
management.

| When
to Use
Focus groups are valuable for open-ended group discussions
on a range of issues and for obtaining in-depth information
about perceptions and concerns from a group. This format
is not always useful for collecting information on individual
participant outcomes, but may be used effectively to
assess participants' perceptions of a program's strengths,
limitations, and effects.1
Focus groups are especially useful when you suspect
that respondents will be more willing to discuss the
topic in a group setting. For example, sometimes persons
are unwilling to mention a program's problems when they
are talking one-on-one with an interviewer from the
program. In a group, they may feel supported by the
presence of others who have interacted with the program.
Focus groups are also useful when you have reason to
believe that some members of the group will be able
to help get other members talking. This can be especially
valuable if there are cultural, socioeconomic, or other
obvious differences between the group members and those
running the program.

Group Validity and Reliability
As with individual interviews, focus groups are designed
to obtain information regarding personal perceptions
and experiences. Thus, what the group members report
is accepted as a valid representation of their experience,
particularly if it is not challenged by other members
of the group. There are, however, ways you can further
ensure the accuracy of the information.
- Reliability of information obtained
in focus groups can be assessed by returning to a
subject later in the discussion. It can also be assessed
by having several focus groups address the same topic.
Information obtained in one focus group can be tested
in subsequent focus groups by asking about similar
events.
- Validity of the reported information
can sometimes be assessed through comparison with
program documentation. For example, if the members
of a focus group report that the seminar on clean
indoor air did not cover the dangers of secondhand
smoke, this can be verified by reviewing the videotape
of the course. If the tape shows that the dangers
of secondhand smoke were covered, then it will be
helpful to explore what may have caused this topic
not to come to the attention of the attendees. Was
it covered at the wrong time? Was the presentation
such that it did not clearly get its point across?

Group Instruments
Data collection instruments for focus groups are very
similar to those used in individual interviews, but
now they are called "focus group guides." In general,
they contain open-ended questions or topics in semi-structured
or unstructured formats. Rarely are
structured formats used. As with interview guides, the
questions on focus group guides are designed to get
the participants to talk.
A semi-structured focus group guide
might have some specific topic areas and a general order,
as shown below. The group facilitator would follow the
natural course of the conversation and cover each topic
as it came up. The following are some questions one might use in a semi-structured format.
- How did you first learn about Program X?
- Where have you seen or heard information about
the program?
- What do you think is the main purpose of Program
X?
- What factors might influence people to participate
in the program?
- What factors might discourage people from participating
in the program?
- What most needs to be improved about Program
X?
An unstructured focus group would
have only a general subject area to be explored, leaving
as much of the content as possible to the respondents,
and following their lead. The opening question might
introduce the topic as follows:
| "We're designing
a Minority Youth Tobacco Program and would like
your input about what might work best to encourage
minority youth not to use tobacco. What can you
suggest?" |
In addition to the content of the focus groups, it
may also be important to gather classifying information
such as demographics, or attendance at the program.
If so, this information can be gathered from each participant
as he or she arrives, before he or she enters the group.

| Sample
Questions
The following is a set of sample questions a facilitator
might ask a focus group composed of persons from a community
in which a secondhand smoke project is about to be developed.
- What have you heard about the subject of secondhand
smoke?
- Do you think secondhand smoke is a problem? Probe:
Why?/Why not?
- How would you go about starting a program to raise people's
concern about secondhand smoke?
- Who are some people you would include in the planning
process?
- What would you be sure to include in the program?
- What would you be sure to avoid doing in the program?
- Is there anything else you would suggest?
The following is a set of sample questions a facilitator
might ask a focus group composed of persons from the
target audience of an advertising campaign about the
dangers of secondhand smoke in the home:
- Have you seen the new advertisements to get people
to quit smoking in their homes and around their non-smoking
children and loved ones? Probe: Where did
you see these ads?
- What do you think of the ads?
- Do you think more people will quit smoking around
non-smokers as a result of the campaign? Probe:
Why? Why not?
- Who do you think is most likely to notice the advertisements?
- What have you heard about the campaign from children?
Other adults?

| Format
and Logistics
Focus groups can require more organization and planning
than personal interviews because they require the following:
- Coordinating the schedules of more than one respondent
as well as a group facilitator and a group recorder
- Choosing the location that is most convenient to
all participants
- Arranging for recording of all responses
- Trying to keep the discussion on track
Before conducting a focus group, someone will need
to contact each group member to invite him or her to
the group. In some instances, it will also be necessary
to determine a convenient time for the group. At the
initial contact, the group members should be told the
following:
- The general purpose of the focus group
- How long it is expected to take
- That the group will be audio- or videotape recorded
- The steps that will be taken to keep the information
confidential
- Contact information for the facilitator or other
designated individual, in case the group member needs
to ask additional questions
Group Size and Type
A total of 4 to 12 people (ideally 6 to 8) should be
recruited for each group. Fewer than 4 people makes
it difficult to generate discussion, and more than 12
people makes it almost impossible for everyone to participate.
Group members should be persons who are similar with
respect to their relationship with the program, and
who view each other as equals.
Location and Environment
Each focus group should take place at a location that
is convenient and comfortable for the group members.
When they arrive, each group member should be greeted and asked to provide any individual information that
is needed such as demographics. They should also be
familiarized with the setting, and the location of food
or beverages (if provided) and restrooms.
Once the group has come together, the facilitator should
take a moment to make sure that the group members are
comfortable, and to review the purpose of the focus
group. This should be done using a standard format with
each focus group. After the introduction, the facilitator
can begin to follow the questions/topics on the focus
group guide.
Follow up
When the focus group guide has been completely covered
it is important to ask the members if there is any additional
information they would like to provide, ask if they
have any remaining questions for the facilitator, and
thank them for participating. If there is an incentive
for participation (e.g., $10 payment), let the members
know how they will receive this, and leave them with
information regarding how to reach the interviewer in
case additional questions arise.
Transcription
Once the focus group has been concluded, it should
be transcribed verbatim from the tape. The name of the
members and/or other identifying persons (such as partners
or children) or identifying information (such as address)
should be disguised or omitted in the transcripts. Once
the transcripts are completed and verified, the tape
can be destroyed. This will protect the privacy of the
group members. The verbatim comments of the group members
will be the information that is used in the analysis
of the focus groups.
In summary, here are the highlights of what you should
do to get the most out of your focus group.
- Plan on conducting three or more focus groups because
different combinations of people yield different perspectives.
- Ideally, focus groups consist of six to eight people
who are likely to regard each other as equals.
- Select five or six general questions to guide open-ended
discussions lasting about an hour and a half.
- As with personal interviews, focus-group discussions
should be audio- or videotaped and transcribed verbatim.
- Have one facilitator guide the discussion and another
person present to assist with facilitation and take
detailed notes. Less detailed notes may also be taken
on a flip-chart for all to see. This can give group
members the chance to add anything they think is important.
- Establish some rules for how the group responds
to questions so that all members have the chance to
contribute.
- Watch your time so that you get through all questions
in the time you have. Try to keep the discussion on
track.
- Soon after each focus group is finished, summarize
in writing the main points that emerged in response
to each of the general questions.
